As well as looking great in your backyard, Jumpflex® 14 ft trampolines are designed to stand the test of time. Jumpflex® metal components undergo a 6-layer rust-proofing and durability process.

All metal components are galvanised inside and out with a hard-wearing zinc coating. Visible sections are finished with a UV-resistant black powder coating. This ensures Jumpflex® trampolines will remain a property feature you'll be proud of.

More space between you and the poles

More bouncing, less risk

With our unique patented design, the poles curve away from the trampoline, so you can go crazy! Flip, spin, twirl and do all the stuff that makes bouncing so much fun, with less risk.
